UNITED STATES HENRY MCDERMOTT, OF

COlLER-HEAD OF LOlVELL, MASSACHUSETTS.

CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 631,319, dated August 22, 1899.

Application filed January 3, 1899 Serial No. 700,942. (No model.)

To all whmn [It ll'I/CLZ/ concern:

Be it known that I, HENRY MCDERMOTT, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Coiler-Heads of Carding-Engines, of which the following isa specification.

My invention relates to improvements in the coiler-head of a carding-engine, of which the top is constructed with an aperture exposing the operating machinery of the coiler, said aperture being covered or uncovered at will either by a straight slide or by an elongation of the trumpet-head so fitted at the end which is over the coiler calender-rolls asto permit the trumpet to be swung horizontally without altering the relative position of the trumpet to the said rolls; and the objects of.

my'invention are to allow the machinery on the inside of the coiler-head to be inspected or oiled without stopping the carding-engine, the coiling machinery, or breaking the sliver as it runs from the carding-machine across the top of the coiler-head to the coiler. I attain these objects in the manner illustrated by the accompanying drawings, in which- Figure 1 is a top view of the machine as it appears with the aperture in the top closed by the swinging trumpet-head; Fig. 2, a top view of the machine as it appears with the trumpet-head swung away from the coilerhead, so as to fully uncover the aperture and expose the inside machinery. Fig. 3 is a vertical section of the coiler-head, showing the manner of attaching the trumpet-head to the coiler-head and the passage of the sliver without interference from the moving trumpethead.

Similar letters refer to similar parts throughout the several views.

a is the swinging trumpet-head.

b is the trumpet-guide, through which the sliver runs to the coiler and always maintains its relative position whether the trumpethead be closed or open.

a is the back-stop, which holds the trumpet-head in position when closed and also keeps the sliver elevated above the end of the trumpet.

d is the stationary top of the coiler-head.

e is the sliver.

f is the washer on the under side of the trumpet-head, attached to the trumpet-head by the screws g g. This arrangement allows the trumpet to swing horizontally, but prevents the trumpet from moving in any other direction.

a: a; y y in Fig. 2 show the opening in the top of the coiler-headfexposing the machinery.

By the construction of the various coilerheads now in use it is necessary to stop the whole machine in order to inspect or oil the machinery used in driving a coiler for a carding-engine, or their construction is of sucha clumsy or intricate nature that they are easily broken or constantly out of repair, thereby. making considerable waste, loss of time, and breaking the sliver. By my invention these defects are overcome, the sliver remains unbroken during the process of oiling or inspecting, and the mechanism is of the Simplest kind.

An opening or aperture is cut in the top of the coiler-head over the machinery which it is necessary to oil or inspect, and this opening when not in use for the above purpose is tightly closed by a horizontal slide or by a special construction of the trumpet-head, which in most other coiler-heads is an immovable plate attached to the top of the coilerhead or to the bearings of the calender rolls, while in my invention the trumpet-head is movable horizontally, but prevented from moving in any other direction by being screwed on the under side to a washer which overlaps the under surface'of the top of the coiler-head, thereby allowing the trumpethead to swing horizontally, but in no other direction and holding the trumpet-guide in its place directly over the coiler calenderrolls; The trumpet-head is extended away from the trumpet-guide and is of sufficient width and length to exactly cover the aperture in the top of the coiler-head, and when it is desired to inspect the gearing and machinery in the coiler-head the trumpet-head is swung to the right or left, so as to fully uncover the said aperture. During this process the sliver continues to run across the opening and into the trumpet-guide and rolls without breakage or interruption and it is unnecessary to stop any part of the machinery.

While I prefer the above-described method of constructing my improvement, I do not confine my invention to the precise kind of l or coverattached thereto and revoluble there- 10 sliding or swinging cover or aperture herein with to cover and uncover the opening in the described. casing, substantially as described.

What I claim as my invention, and desire In testimony whereof I have aflixed my sig- 5 to cover by Letters Patent, is i nature in presence of two witnesses.
